1. A frequency hopping base station comprising:
- a receiver for receiving a data over a plurality of sets of frequencies from remote units in a predefined coverage area, said coverage area divided into N concentric regions which in turn are divided into M sectors to define M*N concentric sector areas, each concentric sector area being assigned one of said plurality of frequency sets such that for any given concentric sector area a different frequency set is assigned than the frequency sets assigned to all other adjacent concentric sector areas;
a transmitter for transmitting data to a remote unit over a set of frequencies associated with the concentric area in which the remote unit is located.

Abstract
A remote unit transmits data by Frequency hopping over a set of frequencies to a base station. A plurality of antennas at the base station receives the transmitted frequency hopped data. An optimal combining of each antenna'"'"'s received hopped data for a particular frequency is determined. Data is selectively transmitted using the plurality of antennas from the base station to the remote unit over the particular frequency. The selectively transmitting is selected using the optimal combining.
